Abstract: An uplink power control method, a terminal, and a network device are provided, which relates to the field of communications, and is to solve a problem that the terminal cannot reach a maximum transmission power for codebook-based or non-codebook-based uplink multi-antenna transmission in related technologies. The method includes: obtaining an uplink precoding indication; and controlling a value of an uplink transmission power determined according to a power control procedure to remain unchanged, in a case that the uplink precoding indication corresponds to a target precoding indication. Based on the solution of the present disclosure, it is ensured that the maximum uplink transmission power can be reached under part of precoding indications, the coverage of uplink transmission can be improved, and it is not required that all antennas of the terminal can reach the maximum transmission power, thereby reducing the cost.
